Be it known that we, HOMER'DETAR and i WILLIAM Souoonovnn, citizens of the United therein to the accompanying drawing.

tachable axle stub This invention relates to -certain new and useful improvements in axle stubs, and the invention relates more particularly to a deor spindle.

The Invention aims to-dispense with the Welding of axle stubs to an axle, and in this connection we have devised positive and reliable means for detachably connecting a stub or spindle tojan axle and without reducing the strength of the axle. y

Tol this end the invention comprises an axle stub having the usual enlargement or collar at theinner end andwith a conical-threaded cavity in the end of the stub and within the collar, and a correspondingly conicalthreaded stud upon the outer end of the axle adapted to engage the threaded-cavity. We employ in` connection with the improved stubs or spindles a novel form of wrench adapted to be employed in connecting the two parts of the device.

' The above construction, together with the details of construction, will, be hereinafter more fully described and referring `to the drawing accompanying this application, like numerals of referencer designate correspondparts throughout the several viewsyin c Figure 1 is a side elevation of one end of an axle equipped with our improved stub, Fig. 2 is a cross sectional view taken on the end of the stub, Fig. 4'is aside elevation of oneend of the axle, showingstub in section, Fig. 5'is a side .elevation of the stub illustrating our improved wrench thereon, Fig. 6 is a pian of the tool by which the stub is attached 'to the axle, Fig. 7 4is a detailview of the end vided with a collare@ and a ycone shaped screwthreaded end 3i ical cavity within of Fig.. 1 Fig. 3 is a view ofthe inner end formed with an enlarged collar 45, havin a cone-shaped screwthreaded recess 6 forme screw threa ed end 3 of the axle. The stub groove 7, which lubricant by-path for convelying oil o lubricant from one end of t to the other end, to insure all surfaces of the findle or stub being properly lubricated.

may represent anoilin ,or r theike tracted, as at 8 and screw threa ed as at 9, to to receive a tap or nut 10 employed for retainin -a wheel upon the stub or spindle.

In Figs. 5, 6 and 7, of the drawing, we employed for seeming the stub or spindle 4 in engagement with the end of the'axle 1. The wrench consists carrying a sleeve 14 bore of the. sleeve is verse ridge or lug 15 adapted to engage in the wrench is placed thereon.` We believe the is obvious, it sing readily understood that the tap 10 is removed to place the wrench come firmly engaged with the end `of the axle.

The presence of the collar 5 upon the axle mally at that point, and by forming the conthis abnormally strength: cned portion, the strength not materially reduced consequently the full :required strength of the stub or spindle is re-.

the invention, and material efficiency and value of the device. An axle constructed in accordance with this invention therefore is fully as stron as an axle'forged from one sing ejpiecey while' at .the same time tages of the two part axle.

1 "The mannerv in which we. secure the stub or' spindle to the axle dispenses with the ywelding of stubs or spindlesupon the axle anda saving is incurred heretofore.

Suchchanges is provided with .a longitudinally disposed e smaller. en'd ofthe stub or snindle is conhave illustrated a Spanner wrench 1 1 which s of va handleor lever -12 l at its one end and the provided with a transupon the spindle or stub and that the lWrench andstub are rotated until the stub has be,
